WET-PROCESS CEMENT-ERICK MOLD;

Specification of Letters Patent,

Application filed May 6, 1915. Serial No. 26,252.

To all whom it may concern:

Be it known that 1, JOHN BOWEN, a

citizen of the United States, residing at Fort Madison, in the county of Lee and State of Iowa, have invented certain new and useful Improvements in Wet-Process Cement-Brick Molds; and I do hereby declare the following to be a full, clear, and exact description object is to provide av mold, every part of:

which is constructed of metal and interlocked together to form a plurality of molding spaces.

A further object is to provide removable side walls'and partitions so that they may be removed from engagement with the molded objects when desired. And a further object is to provide suitable bracing members in connection with parts of the mold.

Other objects and advantages will be hereinafter more particularly set forth and pointed out in the accompanying specification.

In the accompanying drawings which are made a part of this application, Figure 1 is a perspective view of the mold in operative position, Fig. 2 is a transverse vertical sectional view thereof, Fig. 3 is a fragmentary perspective View of one of the end walls, Fig. 4 is a similar view of one of the side walls, and Fig. 5 is a fragmentary perspec tive view of one end of the base of the mold.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 in dicates the base of the mold and 2 the up.- wardly extending flanges thereof, a portion of the metal between the base proper and flanges being doubled upon itself to form a reinforcing rib 3 which rib entirely sur rounds the base 1.

Extending longitudinally of the base 1. are side walls 4 and a partition wall 5, the

lower edges of which extend between the flanges 2 and rest upon the base 1, the ends of the walls 4 and 5 above the flanges having extensions 6 and 7 respectively which project beyond the flanges.

Extending downwardly from the upper edges of the side walls 4 and 5 and extending substantially onehalf the depth thereof, are slots 8 with which interlock the end Patented Nov. 2, 1915.

walls 9 and transverse partition wall 10,

said end and partition walls having slots ll extending upwardly from their lower edges to receive the solid portions of the Side walls and partition wall when said walls are interlocked with each other, said end walls and partition wall having extensions 12 and 13 respectively at their ends which project beyond the flanges2 and the side walls of the mold. V i

In order to reinforce the extensions of said walls, reinforcing clips 14, 15, 16 and 17 are attached respectively to the exten .sions 6, 7, 12 and 13, the clips 15, 16 and 17 having wings 18, 19 and 20 respectively, which wings are extended at right angles from each side of the extensions with which they are engaged and bear against the parts 7 with which the members carrying the same are interlocked, thus strongly reinforcing and bracing these parts at their weakest point. The clips 14 at the ends of the side walls 4 have but one wing member 21, the outside wing member and a portion of the clip being omitted to provide space for the wings 16 carried by the extensions of the end walls 9. In assembling the molds the side and partition walls 4 and 5 are placed in position upon the base 1 when the end walls 9 and partition wall 10 are engaged therewith. The wings of the end and transverse partition walls engaging the outer faces of the side walls 4, while the wings of the side walls 4 and partition wall 5 engage the outer faces of the end walls 9. said Wings greatly reinforcing the parts with which they engage and lending rigidity thereto. -After the side walls and partitions are thus set up, any suitable substance may be molded therein such as cement or concrete blocks or bricks and by properly constructing the faces of the various walls, the molded parts may be provided with fancy surfaces or may be left smooth as desired. After the molded article has become properly set, the side and end walls and partitions may be easily removed and the molded article left resting upon the base until it is thoroughly cured, or after they have become sufliciently hardened may be removed from the base to any suitable point.

It will further be seen that in view of the factthat every part of the device is constructed of metal, it will be extremely light for handling and yet remain strong and durable and practically indestructible from use and it will also be seen that the various parts can be quickly assembled for molding purposes or removed from around the molded bricks and again set up for use.

It will likewise be seen that any number of walls may be provided for increasing the number of bricks which may be molded at the same time and additional partition walls may be provided to form the bricks in any desired length.

What I claim is 1. A mold comprising a base member having upwardly extending flanges and a rib surrounding the base member, a plurality of 'walls having interlocking slots therein and extensions at their ends and. reinforcing means on said extenslons.

A mold comprlsing a base member having its edges bent over to form a reinforcing rib, flanges extending upwardly from the Copies of this patent may be obtained for rib, a plurality of interlocking walls forming compartments above the base, said Walls tended above and beyond the flanges, reinforcing clips on said extensions, and wings radiating from the clips and engaging the faces of the parts cooperating therewith.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
